Alex got her degree from the University of Notre Dame in 2022 after finishing her dissertation on the variation in brown adipose tissue thermogenesis and its effects on metabolic health markers in adults from Samoa. She is currently a postdoctoral fellow at Pennington Biomedical Research Center working on the Military Health and Nutrition Examinations Study (MHANES) (PI: Dr. Claire Berryman). In collaboration with the US Army Research Institute of Environmental Medicine, her work with MHANES examines how the interactions between environmental (i.e. temperature, altitude), behavioral (i.e. physical activity, nutrition, sleep), and physiological (i.e. body composition, energy expenditure, metabolic health markers) factors affect health and performance in active-duty service members. She frequently collaborate with colleagues on anthropological research projects focusing on the effects of physiological adaptations/adjustments to the extremes and is passionate about bringing anthropological perspectives to clinical and military-focused research. ------------------------------ Find the paper discussed in this episode: Sarma, M.

Jake Aronoff is a human biologist studying immune function and aging from an evolutionary and ecological perspective. During his PhD, he studied how stress and social inequality impacts inflammation and immunosenescence in the Philippines and US. He is currently a postdoctoral researcher at ASU studying inflammation and aging with Ben Trumble and the Tsimane Health and Life History Project. These studies focus on the development of chronic inflammation in later life (inflammaging), the links between metabolic and immune function (immunometabolism and meta-inflammation), and the relationship between infections, inflammation, and brain aging. His research also utilizes life history theory and energetic trade-offs to understand complex changes in biological functioning in later life, like the simultaneous occurrence of inflammaging and immunosenescence. ------------------------------ Find the paper discussed in this episode: Aronoff, J.
